uclibc does not export __mempcpy like glibc so we alias it here.
This patch may make sense for upstream but elfutils uses more
glibc specific features like obstack_printf which are missing in
uclibc they need to be fixed along to make it work all the way

Upstream-Status: Inappropriate[Elfutils uses more glibc specific features]
